The machine of which this invention forms a part is designed for thepurpose of making dust mops, or similar articles, by the twisting ofstrands of cotton or other suitable mate rial between wires constitutinga core, the particular invention forming the subject matter of this casecomprising mechanism for controlling the twisting operation, but inconnection with the illustration of this mechanism other" partscomprising the machine as a whole are shown to some extent, some ofwhich parts are not specifically referred to in the description herein,but which parts will be found more specifically set forth and describedin a copending application of Serial Number 120,358, filed July 3, 1926,to another invention embodied in the same machine, and to whichreference is hereby made for such understanding as may be desired ofparts shown herein but not specifically comprising a part of the presentinvent-ion.

In the accompanying drawings the numeral 10 denotes the base of thisimproved machine having standards 11 risingtherefrom and com prising theends of the machine frame as a whole, said standards being connected bya beam 12 extending from one to the other of said standards and securedthereto at the upper portion thereof. A bracket 13 comprising uprights14 is secured to the upper surface of the beam 12, this bracket in factcomprising the head stock of the machine and including a spindle 15mounted for longitudinal movement in a clamp sleeve 16 having a flaredend or mouth to receive chuck jaws 17 of spring formation secured tosaidspindle and adapt 'ed to be closed when drawn into the clampslecve byendwise movement of said spindle, in a manner that will be readilyunderstood. Said clamp sleeve is rotatably mounted in bearings in theupper ends of the uprights 14 and a chuck aw clamping collar 18 ismounted for endwise movement on said clamp sleeve to actuate jawclamping levers 19 pivotally mounted in ai c'lamp lever support 20secured to an adjusting block 21 attached to the he slide 23 maybeactuated as by means of a hand lever 25pivotally mounted on the bracket13 and having a toothed end in engagement with a rack on saidsliue, asshown in Figure 1 of the drawings. The jaws 17 are adapted to grasp theends of wires 26 between which the mass 270i mop material has beenplaced in any desired manner, usually by a mechanical operatioin-saidwires and mass resting upon a table 28 pivotally supmported by arms 29extendingupwardly from the front of the beam 'l2 and as shown in Figure10 of the drawings. The table is connected by a rod 30 with a foottreadle 31, said parts being held in their upward positions as bymeansof a spring 32,,and the treadle being pivotally supported by the ends 11of the main frame.

A tail stock 33 is mountedfor sliding move ment on the'beam 12 at thatend thereof opposite the head stock, said tail stock'having a fixedholdin 'aw 34 and )ivoted holdin s l l I a: aw 35, the latter beingoperated as by means of a cam 36-on a jaw clamping shaft 37 to clamp theends of the wires 26 while being twisted, said shaft 37 being verticallymount to a shaft 41 supporting the handle 25, from v en in the tailstock and having pinion 88 in mesh with a rack at one end of aconnecting rod-39 that also has a rack at its opposite end in mesh withthe teeth of a pinion 40 secured which it will be seen that the handle25 is connected to simultaneously operate the clamping jaws on both thehead and tail stocks. alsobe connected by a shart 13anuintermesl'iingpinions, as shownin-Figures 5 and 8,

as a means for manual operation of the clamp jaws from the tail stockwhen such may be desired.

The tail stock may be held at the backward limit of its movement bymeans of a weight supportedfby a flexible connection over a sheaveandattached to the tail stock, and a cushioning-devicei l5 of anysuitable construction may be employed, it de ired, to retard movement ofthe tail stock backwardly.

This invention has much to do with the mechanism for controlling tl ewinding operation of the machine hereinbefore de- A handle l2 on thetail stock may scribed, and to this end a driving pulley 46 is securedto a driving sleeve 47 rotatably mounted in a bearing in the upper endof one of the standards 11, and as shown in Figure 7 of the drawings,said pulley being driven as by means of a belt 48 extending from anysuitable source of power, as "from a motor mounted on the frame of themachine. Said pulley has in its hub a recess to receive one member 19 ofa twisting clutch, the other member 50 of said clutch being mounted on ethe spindle 15 and splined thereto to permit novement of said spindleendwise independently of the clutch member. This clutch is of the wellknown type of roller clutches and that comprise rollers 51 mounted inwedge shaped spaces between the two clutch members and controlled intheir movements by means of spacers 52 projecting from a clutch actuator53 mounted on the clutch member 50 and independently rotatable thereonto a limited extent. This actuator has recesses 5% for springs 55, oneend ofeach of said springs being secured to the actuator and the otherend 01 each of said springs being secured to a flange 56 on the clutchmember 50, whereby by the action of said springs said clutch member andactuator are caused to rotate in opposite directions to move the rollers51 into the narrow part of the we lge shaped spaces and therebyfconnectthe clutch members for simultaneous rotation. T he actuator hasa stopnose 57 positioned to engage a clutch disengaging lever 58 secured to arock shaft 59 mounted in bearings on the bracket 15 and having a clutchdisengaging arm 60 containing a spring pressed plunger 61 pivotallyattached to a clutch actuating finger 62 mounted on a pivot on thebracket 18 with its free end projecting into a hole in a spring pressedclutch actuating rod 63 mounted. for reciprocating movement in thebracket 13 and on the beam 12, as shown in Figures 1, 7 and 12 of thedrawings.-

A spring pressed clutch controlling rod 64 is mounted for endwisereciprocating movement on the'beam 12 in the path of movement of thetail stock and as shown in Figures 4 to 6, 8 and 9 of the drawings, theother end of said rod being adapted to encounter one end of a clutchcont-rolling lever 65 pivotally supported on the beam 12 andadapted tobe engaged by a detent 66v projecting from a detent lever 67 pivotallysupported on the beam 12 and wit-hone end pivotally connected to a.clutch controlling plunger (38 spring pressed in one direction andmounted in a socket on the beam 12 and in the path of movement of thetable 28, and as shown in Figure 7 of the drawings.

in the operation of the mechanism. the

. .n the position shown in Figures and 2.,

7 1O w res are in place with the mass sop n'i.. "2r1al between them, thehand lever 25 will be swung to the left to the posilill) tion shown inFigures 3 and 4. This movement, aided by the mechanism hereinbetoredescribed, will operate the slide 23 and jaw clamping levers 19 to closethe chuck aws l7, and simultaneously, through the operation of the rod39, the jaws 3l-35 on the tail stock will be forced into contact withthe wires to secure them to said tail stock, the wires just before thisoperation having been closed together in any desired manner, andespecially by the fingers ot' the operator. The treadle 31 being nowdepressed the table 23 will be lowered out of the path of the mopmaterial during the twisting operation, and in its downward movement thetable will strike the plunger 68, thereby depressing it and swingmg thelever 6! to move the detent 66 away from the lever no. This will permitthe spring on the rod 3 to move said rod to the left from the positionshown in Figures 1, 5, (l and 7, thereby swinging the end of the lever(35 into the path of movement of the controlling rod Ga. This movementof the rod 63 also operates to swing the disengaging lever 58, conncctedwith the rod as hereinbetore described from under the nose 5"? oi theclutch actuator 53, thereby perimtting the springs 55 to act upon theclutch member 50 and the actuator 53 to move the rollers 51 into thenarrow part of the wedge shaped space, there by connecting the clutchmembers to effect rotation of the spu le 15 and parts including the jaws17 carried thereby. The twistingof the wires causes them to be shortenedthereby moving the tail stool: 33 toward the head stock and pushingtherod '64: toward and into contact with the lever 65 that at once startsto return as soon as the twisting operation begins being swung on itspivot to the position shown in Figure 6, 'lhis operat on t the rod (33against the tQflSlOiI of its spring to the position shown in Figures 1,3 o 'i', and 12 of the drawings, therew, mov

i J the clutch actuating mechan i into the position shown in said.figures whereby the end of the lever is placed in the path olmovement ofthe The rotation of the spindle continu until the operation ustdescribed takes place, after which, soon as the spindle completes itsrotation, the nose striking said lever will reverse the action of heclutch parts hereinbefore described and the clutch members will bedisengaged the rotation of the spindle will cease. The treadle 31 havingbeen released the detent {36 is located in the path of movement of thelever 65 to retain the parts in these PGSltlOBS, and the hold of thechuck jaws being released by operation of the lllllld lever 25, the tailstool: will. move back unoer the pull of the weight ellin readiness fora repetition o't'the operation.

It is essential. in the operation oi": the ma chine that the clutch jawsl? op with the slot or space between them positioned verand tically sothat the wires may be dropped into said slots. The chuck jaws will be insuch proper position when the nose 57 of the actuator 53 is in contactwith the lever 58. However, when in this position the tendency of thetwisted wires to untwist to some extent will influence backward movementof the clutch member 50 and thereby return movement of the rollers intothe narrow part of the space occupied by them, whereas it is essentialthat the rollers shall remain in the wide part of said space until thenext operation to connect the clutch members.

Owing to the rapid movement of the actuator 53 there is a tendency whenthe nose 57 strikes the end of the lever 58 for the actuator to boundbackwardly and thus move the slot between the jaws from its verticalposition. There is, therefore, provided, a detent mechanism to preventany backward movement of said parts either by bounding or by influenceoi the wires to untwist, this mechanism con'iprising a detent plate 69mounted on the clutch member 50 and held against rotation as by pinningto an upri 'ht ll of the bracket 13. Detent rollers are located in wedgeshaped recesses in the plate 69, as shown in Figure 15 or the drawings,and are engaged by spring pressed plungers 'l'l tending to force saidrollers into the wider parts of said recesse Vi hen the nose strikes theend of the lever 53 any tendency of the actuator to bound or otherwisemove backwa rdly under influence oi the twisted wire to move the clutchmember 50 bacltwardly will at once be resisted by the 'detent rollers,and they will immediately, by reason of such action be moved into thenarrow part of the recesses,

and such backward movem it of either of said members will be immediatelychecked.

t will be noted that the connection between the lever 58 and the rod 63is such that when the arm 60 and finger 62 are swung so that theirpivotal connecting point passes a line extending through the center of:their pivotal supports the action of the spring pressed plunger willcause the arm 60 and linger 62 to be moved quick y, the engagement ofthe end of the finger 62 inthe enlarged socket in the rod 63 permittingthis accelerated movement.

lV hen the tail stock 33 is moved back, af-

ter a twisting operation to secure material between wires, and to itsrearward position, as herembelore described, it is held against forwardmovement until the twisting mechtioned for engagement by a flange 73 onthe rod 30 when the table 28 is moved downward,
